Feet have more sweat glands than any other part of the body.
Sweat + bacteria on the skin = feet that smells like rancid meat.
Steve’s Corrymoor Mohair brand of socks, made out of fleece of angora kid goats, do not trap the bacteria. Apparently, these socks have the ability to remain stink -free even when they are not washed for upto a year. Oh my! They are also extremely comfortable and durable.
